About this field manual

I’m MFesenko, an operations engineer in Moscow documenting the long road from keeping systems alive to understanding why they stay reliable.

Why I write

This is a working notebook for practical SRE lessons: incidents investigated, systems deliberately broken, tools explored, and ideas made clearer by explaining them.

The notes are written for developers moving toward reliability work and for engineers who enjoy learning in public.
